Umphumela wokubambisana kwe-organic tin kanye ne-powder calcium zinc stabilizers ku-polyvinyl chloride (PVC):
Ama-organic tin stabilizer (thiol methyl tin) ayindlela evame ukusetshenziswa yokuzinzisa ukushisa kwe-PVC. Asabela ne-acidic hydrogen chloride (HCl) ku-PVC ukuze akhe usawoti ongeyona ingozi (njenge-tin chloride), ngaleyo ndlela avimbele ukunqwabelana kwe-HCl futhi anciphise ukuwohloka kanye nokuphuzi kwezinto ze-PVC.
I-powder calcium zinc stabilizer iyinhlanganisela ye-calcium ne-zinc salts, evame ukungezwa ngesimo se-fine powder ku-PVC. Ama-ion e-calcium ne-zinc anekhono lokuqinisa i-PVC. Ama-ion e-calcium angakwazi ukuqeda izinto ezi-acidic ezikhiqizwa ku-PVC futhi akhe ama-compound e-calcium salt azinzile. Ama-ion e-zinc asabela ne-hydrogen peroxide (HCl) ku-PVC ukuze akhe ama-compounds angenabungozi futhi avimbele ukuqongelela kwe-HCl.
Uma izithambisi ze-zinc ze-calcium tin kanye ne-powder tin zihlangana ndawonye ku-PVC, zingakhuthazana futhi zithuthukise ikhono lokwelapha i-HCl. I-Organic tin inganikeza ikhono elengeziwe lokudambisa ukubola kwe-HCl eningi ekhiqizwayo, kuyilapho izithambisi ze-calcium zinc eziphuphuphu zinganikeza i-calcium ne-zinc ion eningi, okuvimbela kakhulu ukunqwabelana kwe-HCl. Ngalesi senzo sokusebenzisana, izithambisi ze-zinc ze-calcium tin kanye ne-powder tin zingathuthukisa ukuzinza kokushisa kwezinto ze-PVC, zithuthukise impilo yazo yenkonzo kanye nokuqina kokusebenza.
Kufanele kuqashelwe ukuthi inani kanye nesilinganiso sezinto eziqinisa i-zinc kanye ne-calcium zinc kudingeka kulungiswe ngokufanele ngokwezidingo ezithile kanye nendawo yokusetshenziswa kwemikhiqizo ye-PVC, ukuze kufezwe umphumela omuhle kakhulu wokubambisana. Ngesikhathi esifanayo, kubalulekile ukunaka izinkinga zokuphepha kanye nezemvelo ngesikhathi sokusetshenziswa ukuze kugwenywe imiphumela emibi empilweni yabantu kanye nemvelo.
